DISK FOR TORPEDO -DEFLECTORSL Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed December 22, 1917. Serial No. 208,414.

To all whom it may concern:

Be it known that I, J OSEPII HoLn ND, a citizen of the Republic of Russia, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Disks for Torpedo-Deflectors, of which the following is a specification.

The device set forth in this application is a disk of peculiar design and construction and intended to serve with the torpedo deflector described in my application Serial #184,869 and as a part thereof.

In experimenting with my invention I have discovered that a disk may be designed which will have certain distinct advantages over a flat disk regardless of how the flat disk is padded and the construction of such an improved disk and its method of operation will be fully described as the specification progresses.

The following is .what I consider a good means of carrying out this invention and the accompanying drawings should be referred to for a complete understanding of the specification which follows.

In the drawings:

Figure 1 shows in diagram a ship with my device attached.

Fig. 2 is an elevation of a disk, and

Fig. 3 a side View thereof. Figs. 2 and 3 are on a greatly enlarged scale.

Similar reference numerals indicate like parts in all the figures where they appear.

The boat or ship with which my device may operate and to which my device is at tached may be of any ordinary construction, shape or size; it will not be necessary therefore to describe the boat in detail.

, In Fig. 1, the boat is indicated by the reference character 4, which character will refer to the entire boat.

Means are provided for rotating the disks but as the means for causing the rotation is not specifica1ly claimed in this application it will not be described in detail, it being suflicient to state that I prefer that each oppositely disposed pair of disks should be driven or rotated independently of each other pair.

At 5, I indicate a disk at one side of the boat and directly opposite this disk and upon the other side of the boat another similar disk is arranged and these two disks comprising the pair may both be mounted upon a singleshaft 6.

The reference'characters 5 to 19 indicate similar disks to that already referred to and itwill. be notedthat the disks indicated by the odd numbers 5, 7 9, etc., are upon one plane and the disks indicated by the even numbers 6, 8, 10, etc., are upon a different plane, the disks indicated by the even num' bers being near the hull of the boat and for a greater part behind the disks 5, 7, 9, etc.

Now I will describe the construction of each of the disks.

It will be noted that all of my disks are of the same diameter and I prefer it so because I may more readily standardize their production and make them interchangeable; further than this it is evidently important that all portions of the side of the ship should receive equal protection.

It will be further noted that when fully' laden the disks will be for the most part below the water line and in Fig. 1 the water line is indicated by the reference charac ter W.

Upon the shaft 20 I secure a disk 20 which may be of steel or of iron plate and of any suitable thickness though it is obvious that the weight and strength of this plate must be carefully considered as it is important that the plate withstand every force that may be brought to bear upon it.

Secured to the disk 20 is a cork surface 21. and upon the cork 21, I arrange a plurality of springs 22. A disk 23 of hard rubber or other suitable resistance material is secured to these springs and at the outer end thereof and a rubber cushion 24 is secured to the disk 23.

The cushion 24- is formed with a series of ribs or projections 25, 26, 27, etc., and between these projections are depressions as shown at 28, 29, and 30.

The angle of the depressions between the ribs 25-27 is intended to equal the taper of a torpedo head.

From the description it is thought that the operation of my device will be understood. The disks are constantly rotating and should a torpedo be launched against the boat fitted with my device the projections upon a disk with which it might engage will snub the torpedo and turn its point downward causing it to pass under the boat. The torpedo cannot be discharged as the firing point will find no surface with which to engage, the depth of the recesses between the projections 2527 being sufiicient to allow the contact head of the torpedo to be received therebetween While projections engage the torpedo away from the firing head and deflect it fromits course as described.

Having carefully and fully described my invention What I claim and desire to secure by Letters Patent is 1. A device of the character described having a rigid revoluble disk and a cushioned disk, a plurality of radial projections and depressions upon the outer surface of said cushioned disk and resilient means for zecuring said cushioned disk to said rigid isk.

2. A device of the character described comprising a metal disk a rotatable cork disk upon said metal disk a plurality of springs upon said cork disk, a sheet rubber disk secured to said spring and a cushioned rubber disk secured to said sheet rubber disk, said cushioned rubber disk having a plurality of radial projections and means for supporting the Whole in operative position.

Signed at New York city, in the county and State of New York this 28th day of Nov., 1917.
